Which ensemble is commonly associated with rock or pop music and features electric guitars?

• A. Rock band
• B. Jazz combo
• C. Concert band
• D. Orchestra

Answer: (A)

The main idea here is recognizing which ensemble is defined by rock or pop music and the use of electric guitars. A rock band fits this description best because its typical lineup centers around electric guitars, along with bass, drums, and vocals. The electric guitar is a defining sound in rock and pop, delivering riffs, power chords, and solos that drive the music and overall energy of the performances.

Jazz combos usually lean on improvisation and often use acoustic or jazz-equipped guitars rather than the electric, amplified role that's central to rock. Concert bands and orchestras are built around wind, brass, percussion, and classical string sections, and while they can include guitars, they aren’t characterized by electric guitar-driven rock or pop repertoires. So the ensemble most closely associated with rock or pop and featuring electric guitars is the rock band.
